Bonnie, 31, was engaged to fellow actor Jamie Campbell Bower after they met filming The Deathly Hallows Part 1.

Jamie played a young Gellert Grindelwald in the 2010 film, and went on to star in Fantastic Beasts: The Crimes of Grindelwald in 2018, too.

He also starred in the Twilight movies as vampire Caius Volturi and Vecna in Stranger Things.

Jamie and Bonnie grew close on set, and in 2010, confirmed they were an item.

Just months later, rumours began to circulate that the pair were actually engaged.

And in April the following year, the happy news was confirmed, with Jamie telling The Daily: "I am engaged. I’m very happy. It’s a wonderful, wonderful time."

Sadly, it wasn't meant to be, with the pair splitting in June 2012.

Jamie went on to date Lily Collins on and off until 2018.

It seems some HP fans had totally forgotten about the pair dating, or had totally missed it altogether.

One person wrote on Twitter: "Fun fact: Jamie Campbell Bower actually used to date Bonnie Wright aka the real actress for Ginny."

While another said: "So no one was gonna tell me that Jamie Campbell Bower and Bonnie Wright dated for 3 years????"

And a third added: "Wait Jamie Campbell Bower dated bonnie wright????? Omg."

Bonnie and Jamie weren't the only Harry Potter co-stars to strike up a romance.

ICYMI, Evanna Lynch had a nine-year relationship with one of her co-stars after meeting him on set.

The 31-year-old is best known for her role as Luna Lovegood in the franchise after joining the cast back in 2007 on Harry Potter and the Order of the Phoenix.

And it was on the fifth instalment of the series where Lynch met Robbie Jarvis, who played a younger version of Harry's father James.

Jarvis' time in Harry Potter was very brief as he only appeared during a flashback scene in Harry Potter and the Order of the Phoenix.

But the pair formed a close bond during their time on set and secretly dated until 2015. They split in 2016, but stayed friendly.

Speaking at the premiere of Fantastic Beasts and Where To Find Them, Lynch said: "We're both vegans, so we go to a lot of vegan events together. So yeah, we're good friends."
